This invention relates generally to dispensing devices, and refers more particularly to devices which are principally designed for facilitating the pourin of liquid fuel, such 5 as gasoline from sealed containers into the fuel tanks of motor vehicles.

The invention broadly aims to provide an improved dispensin device whichserves to simultaneously orm an opening in a sealed container and to establish a fluid tight connection with the opening thus formed, to permit the contents thereof to be poured therefrom into a tank or other receiver.

It has been observed that considerable t diculty is encountered in pouring gasoline or other liquid fuels from five-gallon cans or other similar containers into the fuel tanks of motor vehicles, due to the difliculty of disposing the usual pouring spouts in close proximity to the filling opening of the tank, and the present invention, therefore, comprehends a dispensing device which includes a flexible tubular section, such as a length of hose provided with a rigid tubular section at one end thereof which is so constructed as to afford means for readily piercing a sealed container to form an opening therein for discharging the contents therefrom through the iexible section, which latter section may be introduced into the lling opening of the fuel tank.

As a further object, the invention contemplates in a` dispensing device of the character set forth, a rigid tubular section which in addition to 'forming a discharge opening in a sealed container, serves to establish a iuid tight seal to insureagainst leakage of the contents during the pouringl operation.

A further feature of the invention resides in the use of the free end of the flexible section of thedevice as a sheath to cover an protect the pointed'or sharpened end of the rigid section to prevent injury to the person of the user, dulling of they cutting edges of the rigid section and the entrance of dust, dirt or other foreign matter to the interior of the sections.

Other objects of the invention reside in 1929. Serial No. 374,128.

the simplicity of construction and mode of use of the device, the economy with which it may be produced and the general efficiency derived therefrom.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawings: 'y

Figure 1 is a perspective view illustrating the device in juxtaposition to a sealed container.

Figure 2 is a fragmentary sectionaly View illustrating the device forced into the container and operatively associated therewith for. dispensing the contents.

Figure 3 is a fragmentary view illustrating the device applied to the container and in dispensing position.

Figure 4: is a transverse sectional view taken approximately on the line 4 -4 of Figure 2.

Figure 5 is a side view of the device partly in section and illustrating theman? ner in which the free end of the flexible section covers and protects the rigid section.

Figure 6 is a fragmentary sectional view through the dispensing devicein pouring position, particularly illustrating the ventin means.

eferring to the drawings by characters of reference, the dispensing device or spout designated generally by the reference character A, is designed to be associated with a sealed container, such as a can B, as-illustrated, for the purpose of gravitationally dispensing the contents therefrom and pouring the same into the filling opening C of a receiver D. At the present time, containers or cans B suchas illustrated are usually rovided with a spout constituting a part of and sold and packaged with the container or can. These spouts are objectionable for many reasons, principally due to the fact that they occupy considerable space in the storage and shipment of the llans. By providing a dispensing 'device inv accordance with the present invention,

it is, therefore,

- ly spaced apparent that the usual spout will be 'dispensed with and the purchasers of the cans or containers will be provided with a dispensing device constructed in accordance with the invention which may be repeatedly used in connection with cans which are not provided with the dispensing spouts. The dispensing spouts lpreviously referred to which were provided with the can or container were further objectionable in that their size was not sufficient to bring the same in close proximity to the filling opening of fuel ltanks on motor vehicles and, consequently, well as the danger incident thereto, was occasioned in the use of the former.

The dispensing device constituting the subject matter of the present invention con- /sists of a flexible conduit 10, such as a lengthv of canvas hoseor its equivalent which is sufiiciently long to permit of its introduction directly into the filling opening of a receiver when the device is associated with the container. The device .further includes a hol.- low cylindrical member or tube 11 which is telescopically fitted within one end ofthe conduit l0 with a portion thereofv protruding therefrom and formed to provide a pointed terminal 12 having diverging 'cutting edges 13. Preferably, the member 11 is tapered and is of gradually increasing diameter from the outer or free Aend to its opposite end or at least to the juncture of its protruding portion With'the'secured vend of they conduit 10. In practice, suitable fastening means will preferably be provided, such as theI fasteners 14 which are -arranged in circumferentially spaced rela- `tion to extend through the conduit 10 and member 11. The secured end of the conduit 10 forms a shoulder 15y at the juncture thereof with the protruding portion of the member 11, and the protruding portion of the member 11 at this point is preferably provided with external threads 16, .the urpose of which will be hereafter set forth). The protruding portion of the member 11 i-mmediately beyond the threads 16 and slightfrom the shoulder 15 is provided with a circumferentially spaced series of openings 17.

In use and operation, the device is ary ranged in substantially the position illustrated in Figure 1 of the drawings with respect to the container or can B, and by exerting 'a rapid downward pressure on the device, it is obvious that the pointed lterminal 12 will pierce the container while the diverging'cutting edges 13 will function to perforate and remove therefrom and eject into the container a circular portion of the wallj- When the attached end of the conduit 10 which constitutes the shoulder 15 abuts with the 'wall of the containerfthe portion of the member 11 provided with considerable spillage and Waste, as',

would Ientail a loss to the user.

container B is emptied, the dispensing de' the external threads 16 will establish a liquid tight seal with the wall of the opening thus formed, and by inverting or tilting the container B it is apparent that the contents willflow through the member 1l into the conduit. The opposite free end of the conduit may be positioned within the filling opening of a receiver, as clearly illustrated in Flgure 8, so as to avoid spillage of the contents. Thethreaded portion serves to lock the member 11 in the opening against accidental displacement, and it will befound in practice that in order to remove themember 11 from thek opening, it. is

necessary to unscrew the threaded. portion from the openin to detach the device from the container. he opening 17 will serve as a means for completely draining the contents of the container so as to. avoid leaving of any appreciable amount therein which After the vice is removed for subsequent use in connection with other containers. When not l in use, the pointed terminal 12 and cutting edges 13'may be protected against injury to the person or against dulling thereof by telescopically arranging the free opposite end ofthe conduit k10 over the protruding portion of the member 11, as illustrated in Figure 5. This will also serve to prevent dust, dirt or other foreign matter from collecting within the conduit or member 11, as the free end of the the opening 17. The fastening devices 14, in addition to securing the conduit and member 11 together, also serve to prevent any possibility of the removed portion of the container wall from passing through the member 11 into the conduit 10 and possibly finding its way into the receiver. i

In order to provide means for the interior of the conduitll, to facilitate the iiow of the liquid during the pouring operation, a vent 18 is formed in the conduit atv a point between the. attached end or shoulder 15 and the inner endiof the member 11. Suitable means is provided, such as the U-shaped element 19, for forming a passageway 20 between the conduit and the member, which passageway leads from the venting opening 18 to the interior of the conduit beyond the member 11.

From the foregoing, it will thus be seen that an improved dispensingv device has been devised by virtue of which sealed containers may be opened `and their contents dis ensed or poured into a receiver without spi lage orv waste of the contents.

at is claimed is:

1. A dispensing device including a iiexibleconduit and truding end being cut to form a pointed terconduit also covers l one end of, secured to saidv rcondult and protruding therefrom, said pro- Venting minal having diverging cutting edges for perforating a wall of, removing therefrom and ejectin into the container a circular portion of t e wall to afford an outlet opening, the said cylindrical member being .of gradually increasing diameters from its pointed. 'terminal to its juncture with the conduit, whereby to snugly lit the outlet opening formed in the container, the attached end of the conduit presenting a shoulder for limiting the insertion of the member into the container.
